ABS & TRAC ECU
1) Wheel Speed Control
The ABS & TRAC ECU constantly receives signals from 4 speed sensors and calculates the speed of each wheel and
vehicle speed.
During sudden acceleration or driving on a slippery surface, if the drive wheels (front wheels) start to slip, the
difference in speed between the drive wheels are slipping.
Then, the ABS & TRAC ECU executes the right and left independent control of the front wheel brakes, the engine
torque control through fuel cutoff, and shift timing control according to the extent of the slip.
TRAC operation processes are described below.
1. The vehicle speed is determined by way of the rear wheel speed. This speed is then compared to the speed of the
front wheels, which are the drive wheels, to determine the slip condition of the drive wheels (front wheels).
2. The target control speed for the drive wheels is set based on the estimated vehicle speed.
3. If the speed of the front wheels, which are the drive wheels, exceeds the control starting speed, the ABS & TRAC
ECU determines that a slip has occurred and cuts off fuel according to the number of cylinders. By executing
engine torque control and brake control in this manner, the system regulates the speed
so that front wheels attain the target control speed. In addition, the system executes control to
prohibit the shifting of the automatic transaxle at this
time.
4. TRAC control ends when the drive wheels move to non±slippery surface or when the driver releases the
accelerator pedal.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of ºPº position when the
brake pedal is depressed (with the ignition
switch in ºONº position and the lock re-
lease button depressed).
(a) Normal driving
1. Start the engine as instructed in ºHow
to start the engineº in Part 3. The
transmission must be in ºPº or ºNº.
2. With your foot holding down the brake
pedal, shift the selector lever to ºDº.
In ºDº position, the automatic transmission
system will select the most suitable gear
for the running conditions such as normal
cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low, the
transmission will not shift into overdrive
gear even with the overdrive switch on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows:

Turn off the overdrive switch. The ºO/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.

Shift into the º2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the following
speed, and more powerful engine brak-
ing will be obtained.
5S±FE engine 106 km/h (65 mph). . .
1MZ±FE engine 122 km/h (75 mph). .

Shift into the ºLº position. The trans-
mission will downshift to the first gear
When the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be ap-
plied.
5S±FE engine 46 km/h (28 mph). . .
1MZ±FE engine 55 km/h (34 mph). . Vehicles with cruise control'When the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking is not
applied because the cruise control is not
cancelled.
For ways to decrease the vehicle speed,
see ºCruise controlº in this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in º2º or ºLº, you
can start the vehicle in motion as with the
lever in ºDº.
With the selector lever in º2º, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ºLº, the trans-
mission is engaged in the first gear.

(g) Rocking your vehicle if stuck
CAUTION
If your vehicle becomes stuck in
snow, mud, sand, etc., then you may
attempt to rock your vehicle free by
moving it forward and backward. Do
not attempt this procedure if people
or objects are anywhere near the ve-
hicle. During the rocking operation
the vehicle may suddenly move for-
ward or backward as it becomes un-
stuck, causing injury or damage to
nearby people or objects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.
(h) If you cannot shift the selector le-
ver out of ºPº position
If you cannot shift the selector lever from
ºPº position even though the brake pedal
is depressed, use the shift lock override
button. For instructions, see ºIf you cannot
shift automatic transmission selector leverº
in Part 4.
Manual transmission
The shift pattern is conventional as
shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving,
because it will cause clutch trouble. And
do not use the clutch to hold the vehicle
when stopped on an uphill gradeÐuse the
parking brake.
Recommended shifting speeds
The transmission is fully synchronized and
upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the following
speeds:

'99camry U
99
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
Downshift to the appropriate gear if accel-
eration is needed when you are cruising
below the above downshifting speeds.
Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
gear:
gear km/h (mph)
1 52 (32)
2 93 (57)
3 147 (91)
NOTICE
Do not downshift if you are going
faster than the maximum allowable
speed for the next lower gear.
Good driving practice

If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.

When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the fifth gear.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
NOTICE
Make sure the vehicle is completely
stopped before shifting into reverse.
Parking brake
Ty p e A
Ty p e B

'99camry U

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Pull up the lever. For better hold-
ing power, first depress the brake pedal
and hold it while setting the brake.
To release: Pull up the lever slightly,
press the thumb button, and lower.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
Cruise control
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION

To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow±covered) or
winding roads.

Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.
TURNING ON THE SYSTEM
To operate the cruise control, press the
ºCRUISE ON±OFFº button. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another press will turn the system
completely off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the ºCRUISE ON±
OFFº switch off when not using the
cruise control.
